Fix transactional observer methods tests

org.jboss.weld.tests.event.observer.transactional.TransactionalObserversTest doesn't test transactional observer methods correctly.

Every observer method in org.jboss.weld.tests.event.observer.transactional.Pomeranian contains:

if (transaction.getStatus() == STATUS_NO_TRANSACTION) {
                setCorrectTransactionState(true);
}
